Powder bed melting process is a common technique used for high temperature material such as Inconel and Titanium that are used commonly for aerospace and biomedical applications. Research has shown that the texture and microstructure of these materials are heavily dependent upon the build parameters. Common texture observed in most experiments has been a columnar grain structure in the build orientation. Some previous experiments have been conducted to control the local microstructure and grain orientation. This research focused on effect of process parameters such as speed, power and line energy density on the texture. More specifically, EBSD analysis is conducted to evaluate the grain size and grains preferred orientation. As previous experiments has shown columnar growth is a distinguished feature of these builds. The preferred orientation was found to be more significant in some conditions involving different line energy density.
